How can you have a successful relationship with someone if you believe passionately in climate action, but they don’t? The fate of our planet can be a divisive, emotive, even frightening issue. It’s something that’s tearing more and more couples and families apart, experts have told us. It’s not easy getting past those differences with the ones we love, but it is possible. We speak to a couple, as well as a mother and daughter, to find out how. And we ask whether the way we talk to our loved ones about climate change might offer important lessons on how we discuss the issue more broadly.

The impacts of climate change are already being felt around the world. Research shows that some groups are disproportionately affected. Women already face many socioeconomic, cultural, and political inequities, with those living in areas heavily impacted by natural disasters related to climate change, such as floods, drought, and coastal erosion, enduring even worse outcomes. So what can be done to address this?

Billions of dollars have been pumped into the promise of a climate-friendly way of producing meat, but is growing a steak in a lab any better for the planet than rearing a cow on a farm? Supporters of the idea say it will dramatically reduce the impact of livestock, which is responsible for about 15% of the world’s planet-warming gases, as well as returning huge amounts of land to nature. But studies suggest cultivating meat in a lab might actually be worse for the planet, at least in the long-run – we put both claims to the test. Plus, ten years on from the unveiling of the world’s first lab-grown meat, we ask why it’s still only available to buy at one restaurant in Singapore, and only on Thursdays.

If you are planning a trip, but you want to check the climate impact before choosing how to get there, then beware. Google has been seriously underestimating the carbon footprint of plane flights, and overestimating that of some train journeys. And its calculations don’t just appear in its search results, but also feed the sites of more and more online booking companies, like Skyscanner and Booking.com. To be fair, carbon footprints are actually very hard to get right, as the BBC’s Climate Editor, Justin Rowlatt, discovers on his own trip to Rotterdam. On the way out, he takes the Eurostar high-speed train, whose carbon emissions depend on the weather over the North Sea that day. On the way back he catches a plane, whose climate impact… also depends on the day’s weather conditions over the North Sea. So what is Google doing to fix its methodology and can we trust carbon footprint calculations at all? And do passengers even really care that much about the environmental impact of their journey, or should they be made to pay for it directly?

The idea of cities where everything you need on a daily basis can be reached within a quarter of an hour by foot or bike has grown in popularity in recent years, as local authorities adopt more sustainable approaches to urban planning. In theory, by having work, shopping, education, healthcare, and leisure all within a short distance could reduce dependency on cars, improving personal health and lowering carbon emissions. But the idea of adapting cities in this way hasn’t been universally-welcomed.
